+         Some architectures require 64 bit accesses to be 64 bit
+         aligned, which also requires structs containing 64 bit values
+         to be 64 bit aligned too. This includes some 32 bit
+         architectures which can do 64 bit accesses, as well as 64 bit
+         architectures without unaligned access.
